if the emulator is TI-MSP-FET(in IAR for arm V7.60), there is the option to erase Info memory or not, but emulator J-Link doesn't have the option.

There might be a race condition between the main loop and the interrupt. In any case, this code does not look like the example in figure 35 of the Programmer's Guide; please try that first.

Does your application really need to perform the sprintf inside the UART ISR? If possible it would be better to run the sprintf in mainline code, filling a buffer that is just read by the ISR. That...

Link to your keypad is recommended. Most of the time a 4x4 matrix involves scanning (providing power) to the column. while reading the rows. Double key press will confuse it.

The FPU certainly makes floating point arithmetic cheap; the hidden cost is the need to save/restore the FP context (17 words) at every interrupt. Lazy-save helps with this, but if the ISR uses...
View ArticleForum Post: For COMP_E, is it possible to output CEVREF to C1 pin?
Hi all, I am thinking of a crazy idea to monitor battery voltage through the COMP_E module in MSP430FR6972 . One of the steps is to output CEVREF to a capacitor connected with pin C1. The capacitor is...

If there is no such option, you may write code to erase it when you run that code. I think this is not difficult by calling the ROM_FlashCtl function to do it. See Timothy Logan’s reply to...

Using CERS_0 and CERS_1 at the same time does not make sense. CESHORT is in the wrong register.
